Abstract

PCT No. PCT/SE82/00112 Sec. 371 Date Dec. 6, 1982 Sec. 102(e) Date Dec. 6, 1982 PCT Filed Apr. 6, 1982 PCT Pub. No. WO82/03738 PCT Pub. Date Oct. 28, 1982.A direct current magnetized hybrid transformer in a telephone line repeater has both its primary windings magnetically coupled to two pairs of secondary windings, one pair creating the four-wire path in the repeater and the second pair being connected to a balance impedance. The primary windings are each divided into two parts with a like number of turns. The feeding voltage source included in the repeater is connected between the connection points common for the winding parts.
